Separatist authorities in Georgia's breakaway province of Abkhazia mobilized the army and called up reservists Sunday to drive Georgian government forces out of the small part of the province still under Georgian control. The move dramatically raises the stakes in the conflict between Georgia and Russia over another separatist province, South Ossetia. With most Georgian troops concentrated on fighting Russian troops in South Ossetia, it could be hard for Georgia to repel the Abkhazian offensive. In addition, Russia troops were seen moving through Abkahzia toward the border with Georgia. Abkhazia's President Sergei Bagapsh said he issued a decree putting the province's troops on high alert and mobilizing some reservists after Georgia launched a military campaign to regain control over South Ossetia.
